Can anyone point me to a good map of Monomoy?

I've been using this site, it seems pretty good. Can't vouch for the accuracy of the ever changing sand spits/Islands.

That is one scary chart. Boats U.S. and E&B both carry decent and fairly recent charts of the area. None are any good for navigating, IMO. Go when the light is good and the tide is rising and you shouldn't get in any real trouble as a result of naviguessing. sR
